Problems solved by technology

Since the size of VR resources is generally larger than 100 megabytes and takes up a lot of space, it takes a lot of space and time to load them into the memory for encryption. Therefore, most of the existing VR resources are in an unencrypted state. use, it is difficult to protect the rights and interests of service providers

Embodiment 1

[0055] This embodiment provides a security protection method for VR resources, including:

[0056] S1. Encrypt the VR resource stored on the disk by means of a memory-mapped file to obtain an encrypted file. Specifically:

[0057] S11. A preset key information table; the key information table stores a key corresponding to each encryption operation.

[0058] S12. Obtain the startup time of the system, and obtain the first key.

[0059] S13. Obtain the key corresponding to the last encryption operation from the key information table to obtain the second key.

[0060] S14. Using the first key and the second key as input parameters of a preset random algorithm, calculate a random value.

[0061] Optionally, the random algorithm is an elliptic algorithm.

[0062] S15. Set a start encryption position and an end encryption position corresponding to the VR resource according to the random value to obtain an encryption interval.

[0063] For example: Get the byte size of VR resour...

Embodiment 2

[0072] This embodiment provides a security protection terminal for VR resources, including one or more processors 1 and a memory 2, the memory 2 stores a program, and is configured to be executed by the one or more processors 1 in the following steps :

[0073] S1. Encrypt the VR resource stored on the disk by means of a memory-mapped file to obtain an encrypted file. Specifically:

[0074] S11. A preset key information table; the key information table stores a key corresponding to each encryption operation.

[0075] S12. Obtain the startup time of the system, and obtain the first key.

[0076] S13. Obtain the key corresponding to the last encryption operation from the key information table to obtain the second key.

[0077] S14. Using the first key and the second key as input parameters of a preset random algorithm, calculate a random value.

[0078] Optionally, the random algorithm is an elliptic algorithm.

[0079] S15. Set a start encryption position and an end encryp...

Abstract

The present invention relates to the field of data processing, in particular to a VR resource security protection method and terminal. The present invention encrypts the VR resources stored on the disk by means of memory mapping files to obtain encrypted files; and synchronizes the encrypted files to the client. Realized reducing the space and time occupied in the process of encrypting VR resources.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a VR resource security protection method and terminal. Background technique [0002] With the popularity of VR (Virtual Reality) technology, many service providers provide various VR resources for users to use in different scenarios. Among them, the more popular are VR resources for teaching and games. Because the size of VR resources is generally larger than 100 megabytes and takes up a lot of space, it takes a lot of space and time to load them into the memory for encryption. Therefore, most of the existing VR resources are in an unencrypted state. It is difficult to protect the rights and interests of service providers. Contents of the invention [0003] The technical problem to be solved by the present invention is: how to reduce the space and time occupied in the process of encrypting VR resources. [0004] In order to solve the problems of the technologies descri...
